Answer 1

Answer:

For the first 35 km, speed was 15Km/hr

For the second 35 km, speed was 30 Km/hr

Step-by-step explanation:

Given

Distance covered = 70 km, Time taken= 3.5 hours

For the first half i.e. for the first 35 kms, speed was Xkm/hr

For the second half i.e. the second 35 kms, speed was twice the speed in first half i.e. 2X km/hr

Solution: For the first half time taken will be

Time = Distance/Speed

Time = 35/X

For the second half

Time= 35/2X

total time 35/2X + 35/X = 105/2X hours

105/2X = 3.5

X = 105/(2*3.5)

X = 15 Km/Hr
