(A) 65 years and 36 years
(B) 67 years and 19 years
(C) 86 years and 48 years
(D) 43 years and 24 years
You selected
160 km
Correct Answer
200 km
Solution And Explanation
Solution
Given,
Distance = 100 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
= 100/10 = 10 km/h
Thus, speed = 10 km/h
Calculation of the distance in the given time using formula
Formula to find the distance
Distance = Speed × Time
= 10 km/h × 20 hour = 200 km
Thus, the distance covered in the given time = 200 km Answer
Method (2) Using Unitary Method
Calculation of the Distance using formula
Given,
Distance = 100 km
Time = 10 hour
Thus, distance covers in 20 hour = ?
∵ In 10 hours the distance covered = 100 km
∴ In 1 hour the distance covered = 100/10 km
∴ In 20 hours the distance covered
= 100/10 × 20 km
= 100 × 20/10 km
= 2000/10 = 200 km
Thus, the distance covered in the given time = 200 km Answer
