Question:
Find the distance covered by an athlete in 25 hours if it covers a distance of 78 km in 15 hours.
Correct Answer
130 km
Solution And Explanation
Solution
Given,
Distance = 78 km
Time = 15 hour
Thus, distance covers in 25 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
= 78/15 = 5.2 km/h
Thus, speed = 5.2 km/h
Calculation of the distance in the given time using formula
Formula to find the distance
Distance = Speed × Time
= 5.2 km/h × 25 hour = 130 km
Thus, the distance covered in the given time = 130 km Answer
Method (2) Using Unitary Method
Calculation of the Distance using formula
Given,
Distance = 78 km
Time = 15 hour
Thus, distance covers in 25 hour = ?
∵ In 15 hours the distance covered = 78 km
∴ In 1 hour the distance covered = 78/15 km
∴ In 25 hours the distance covered
= 78/15 × 25 km
= 78 × 25/15 km
= 1950/15 = 130 km
Thus, the distance covered in the given time = 130 km Answer
