MCQs Math


Question:     At a certain speed a scooty covers a distance of 84 km in 4 hours. How much distance will it cover in 5 hour?


Correct Answer  105 km

Solution And Explanation

Solution

Given,

Distance = 84 km

Time = 4 hour

Thus, distance covers in 5 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

= 84/4 = 21 km/h

Thus, speed = 21 km/h

Calculation of the distance in the given time using formula

Formula to find the distance

Distance = Speed × Time

= 21 km/h × 5 hour = 105 km

Thus, the distance covered in the given time = 105 km Answer

Method (2) Using Unitary Method

Calculation of the Distance using formula

Given,

Distance = 84 km

Time = 4 hour

Thus, distance covers in 5 hour = ?

∵ In 4 hours the distance covered = 84 km

∴ In 1 hour the distance covered = 84/4 km

∴ In 5 hours the distance covered

= 84/4 × 5 km

= 84 × 5/4 km

= 420/4 = 105 km

Thus, the distance covered in the given time = 105 km Answer
