Question : Find the distance covered by a cricket ball in 27 hours if it covers a distance of 68 km in 17 hours.
Correct Answer 108 km
Solution & Explanation
Solution
Given,
Distance = 68 km
Time = 17 hour
Thus, distance covers in 27 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
= 68/17 = 4 km/h
Thus, speed = 4 km/h
Calculation of the distance in the given time using formula
Formula to find the distance
Distance = Speed × Time
= 4 km/h × 27 hour = 108 km
Thus, the distance covered in the given time = 108 km Answer
Method (2) Using Unitary Method
Calculation of the Distance using formula
Given,
Distance = 68 km
Time = 17 hour
Thus, distance covers in 27 hour = ?
∵ In 17 hours the distance covered = 68 km
∴ In 1 hour the distance covered = 68/17 km
∴ In 27 hours the distance covered
= 68/17 × 27 km
= 68 × 27/17 km
= 1836/17 = 108 km
Thus, the distance covered in the given time = 108 km Answer
