Question

a motorist travelled from town A To Town b at an average speed of 54 km per hour on his return journey his average speed was 60 km per hour if the speed total time taken is 9 1/2 hours find the distance between the two towns

Answer 1

Answer:

Let  the distance between the town A and B =X

Total Time =

X/54 + X/ 60 = 19/20

10x +9x /540 = 19 / 2

20x+ 18x = 19 × 540

38x = 10260

X = 10260/38

X = 270 Ans.

Distance between Town A and Town B = 270

Answer 2

Answer: x= 63

Step-by-step explanation:

Let the speed of one motorcycle1 be x.

Then motorcycle2 will be x+7 ((7 kmph faster))

AFTER TWO HOURS

Motorcycle1: 2×x

Motorcycle2: 2×x+7

2x + 2(x+7)+ 34 =300

2x + 2x+14 + 34=300

4x + 48 =300

4x= 300- 48

4x= 252

x= 252÷4

x= 63

Therefore motorcycle1 is at a speed of 63kmph while motorcycle2 is at a speed of 63+7=70 kmph.
