Question

a car moves with a speed of 40m/s for 10s and then with a speed of 60m/s for the next 10s. the total distance covered by the car is :
a) 1000 m
b) 250 m
c) 150 m
d) 2000 m
​

Answer 1

Step-by-step explanation:

first 10s

distance covered by the car is 400m

next 10s

distance covered by the car is 600m

total distance covered by the car is 600+400=1000m

Answer 2

1000m is correct

Correct Question:a car moves with a speed of 40m/s for 10s and then with a speed of 60m/s for the next 10s. the total distance covered by the car is ?

Step by step explanation:-

Given:

Speed of car in first 10 sec = 40 m/s

Speed of car in first 10 sec = 60 m/s

Formula:

Distance covered = speed × Time taken

Approach:

•we first find the distance of individual distance covered

•then, we add the both

Let's begin:-

Solution:

Distance covered = 40 x 10=400m

Speed of car in next 10 sec = 60 m/s

Distance covered = 60× 10=600m

∴ Total distance covered = (400+600)m = 1000m

∴ 1000m is correct
