please.fast ​

Answer 1

This is a example but not the same

60 mins to covered main road of 100kms(1), and 30 mins to covered side road of 20kms(2).

note: distance 100kms = 100000 meters, and 20kms = 20000 meters # time 60 mins = 3600 seconds; and 30 mins = 1800 seconds.

1. 100000 meters ÷ 3600 seconds = 27.7777778 m/s.

2. 20000 meters ÷ 1800 seconds = 11.1111111 m/s.

the average speed is 1+2 divide by 2, thus 27.7777778 m/s + 11.1111111 m/s. = 38.8888889 m/s.

38.8888889 m/s ÷ 2 = 19.4444444 m/s.

therefore, the average speed is 19.4444444 m/s.
