At 11 58, Hilda cycled from the playground towards the clinic while Tiffany cycled from the clinic towards the playground. At 12 13, the two cyclists passed each other. 13 minutes later, Hilda reached clinic but Tiffany was 976 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the clinic and the playground in km.
(a)
From 11 58 to 12 13 = 15 min
Combined speed of the two cyclists
= 976 ÷ (15 - 13)
= 488 m/min
(b)
Distance between the clinic and the playground
= 15 x 488
= 7320 m
1000 m = 1 km
7320 m = 7.32 km
Distance between the clinic and the playground = 7.32 km
Answer(s): (a) 488 m/min; (b) 7.32 km
