Answer:
DE = 86
EF = 84
Step-by-step explanation:
We assume that point E lies on segment DF, so that ...
DE + EF = DF
(3x +20) +(2x +40) = 170
5x = 110 . . . . . . . . . . . . . . . collect terms, subtract 60
x = 22 . . . . . . . . . . . . divide by 5
DE = 3×22 +20 = 66 +20 = 86
EF = 2×22 +40 = 44 +40 = 84

Answer:
Step-by-step explanation:
<u>We know that:</u>
<u>Solution:</u>
- 30 kilometers = 1 hour
- => 30 x 21/2 kilometers = 21/2 hours
- => 15 x 21 kilometers = 21/2 hours
- => 315 kilometers = 21/2 hours
Hence, in 21/2 hours, the cyclist rides 315 kilometers.
