MCQs Math


Question:     Find the distance covered by a ball in 26 hours if it covers a distance of 72 km in 16 hours.


Correct Answer  117 km

Solution And Explanation

Solution

Given,

Distance = 72 km

Time = 16 hour

Thus, distance covers in 26 hour = ?

Here the speed and time are given. So, we need to find the speed to calculate the distance covers in the given time.

Method (1) Using Formula

Calculation of Speed using formula

Formula to find the speed

Speed = Distance/Time

= 72/16 = 4.5 km/h

Thus, speed = 4.5 km/h

Calculation of the distance in the given time using formula

Formula to find the distance

Distance = Speed × Time

= 4.5 km/h × 26 hour = 117 km

Thus, the distance covered in the given time = 117 km Answer

Method (2) Using Unitary Method

Calculation of the Distance using formula

Given,

Distance = 72 km

Time = 16 hour

Thus, distance covers in 26 hour = ?

∵ In 16 hours the distance covered = 72 km

∴ In 1 hour the distance covered = 72/16 km

∴ In 26 hours the distance covered

= 72/16 × 26 km

= 72 × 26/16 km

= 1872/16 = 117 km

Thus, the distance covered in the given time = 117 km Answer
