Answer 1

Heya mate,

Here is your answer,. ⬇️⬇️

${ANSWER :-}$

____________

$<i>$ The school is 14.4 kms away.

So, distance = 14.4 kms = 14400 m.

Amy takes 40 minutes to reach.

40 mins = 40 * 60 = 2400 secs.

Thus, Amy's speed = 14400/2400 m/s

= 144/24 m/s

= 6 m/s. ⬅️

Now, Bill arrives 20 minutes after Amy.

Thus, Bill takes time = 20 + 40 = 60 minutes. = 60*60 = 3600 secs.

Thus, Bill's speed = 14400/3600 m/s

= 144/36 m/s

= 4 m/s. ⬅️

Thus, Amy's average speed is (6 - 4) m/s = 2 m/s faster than Bill's.

➡️ Hence, Amy's average speed is 2 m/s faster than Bill's, for the trip.
