Hey frnd..
Here is your answer...
Let us find the distance..
=> 1st solution:
Distance = speed × time
x = 40 × 2
x = 80 km
=> 2nd solution:
(by same formula)
d = s×t
x =50×3
x =150 km
=> 3rd solution :
(by same formula)
d = s×t
x = 30 × 1
x =30 km
=> Final solution: (for a. question)
Total distance covered by a car = 80 km +150 km+ 30 km
= 260 km
=>Solution ( for b. question)
speed = distance / time
x = 260 / 6 (by adding all hrs)
x = 43.33 km/h
43.33 km/h = 12.036111 m/s
Hope it helped u..
Thank u..
