Question:
Find the distance covered by a car in 20 hours if it covers a distance of 62 km in 10 hours.
Correct Answer
124 km
Solution And Explanation
Solution
Given,
Distance = 62 km
Time = 10 hour
Thus, distance covers in 20 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
= 62/10 = 6.2 km/h
Thus, speed = 6.2 km/h
Calculation of the distance in the given time using formula
Formula to find the distance
Distance = Speed × Time
= 6.2 km/h × 20 hour = 124 km
Thus, the distance covered in the given time = 124 km Answer
Method (2) Using Unitary Method
Calculation of the Distance using formula
Given,
Distance = 62 km
Time = 10 hour
Thus, distance covers in 20 hour = ?
∵ In 10 hours the distance covered = 62 km
∴ In 1 hour the distance covered = 62/10 km
∴ In 20 hours the distance covered
= 62/10 × 20 km
= 62 × 20/10 km
= 1240/10 = 124 km
Thus, the distance covered in the given time = 124 km Answer
