Question

How much distance covered in $12$ hours, if the speed of the car is $74$ km/hr.

Answer 1

Hint: Speed is defined as the ratio of the distance traveled upon the time taken. Here, we are given time taken and the speed of the car so make the required term the subject and simplify for the required value.

Complete step by step solution:
Given that:
Time taken, $t = 12$ hours
Speed of the car, $s = 74$ km/hr
Now,
$\text{Speed}=\dfrac{\text{Distance}}{\text{Time taken}}$
Place the given value in the above equation –
$74 = \dfrac{{dis\tan ce}}{{12}}$
Perform cross multiplication in the above expression, where the denominator of one side is multiplied with the numerator of the opposite side.
Distance $ = 74 \times 12$
Simplify the above equation finding the product of the terms in the above equation
Distance $ = 888$kilometers
Hence,the car travels $888$ kilometers in twelve hours with the speed of $74$km/hr.

Note:
Always check the given units of the quantities and the answer required in the quantities. All the given quantities should be in the same format. Frame the correct mathematical expressions with the given data and find the correlation between the known and the unknown terms. Be good in terms of multiples and the division. Remember the formula for the velocity and the speed remains the same.
