Answer 1

Hello,

Here is your answer by Sujeet

Average speed = 2 x 54 x 60/(54 + 60)

= 6480/114

then,

Total time taken

=19/2

then,

Distance travelled=6480/144*19/2
=3240*19/144
=22.50*19
=427.50



that's all

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.
