Answer 1

1 --- The cyclist's average speed was 18 miles per hour.

2 --- I would travel 280 miles far.

3 --- Your average speed was 52.5 miles per hour.

4 --- You should expect to arrive in Leeds at 11:50 AM.

5 --- The athlete will run 2000 m in 8 minutes and 20 seconds.

6A --- The average speed of the journey is 48 miles per hour.

6B --- It will take him 6 hours and 40 minutes.

Explanation:

1) 90 / 5 = 18

2) 70 x 4 = 280

3) 315 / 6 = 52.5

4) 210 / 90 = 2.3333

0.333 = 0:20

9:30 + 2:20 = 11:50

5) 2000 / 4 = 500

500 / 60 = 8.3333

0.3333 = 0:20

8.3333 = 8:20

6A) 0:45 = 0.75

420 / 8.75 = 48

6B) 420 / 63 = 6.666

6.6666 = 6:40
