Hint: Centimeter is a very small measurement of distance when compared to a mile and at the same time second is a very small measurement of time when compared to an hour. We have to use simple mathematical operations to convert a second per second to a mile per hour. In these types of questions, calculation mistakes are very common.
Complete step by step solution:
According to the question we have to convert 36cm/sec to mph,
And as we know that one hour = seconds = seconds
And we also know that one mile = 160934 centimeter
Now, we have to convert centimeter into mile
cm = mile
cm = mile (Dividing both sides with 160934)
36cm = mile (Multiply both sides with36)
36cm = mile (consider it equation 1)
Now, we have to convert second into hours
Hour = seconds
Second = Hour (Dividing both sides with 3600)
Second = 0.00027 (Consider it as equation 2)
Now, to get the answer just divide equation 1 with equation 2
= mph
Hence, this is our answer
Note: It is very efficient to calculate speed in different units of measurements. Representing the same measurement using different units varies from place to place. We can observe that when we convert a larger unit to a comparative lower unit the numerical value gets increased as compared to the original numerical value and when we convert a lower unit to a comparative larger unit the numerical value gets reduced. This property is shown in this question.
