Atrip is taken that passes through the following points in order
a(0m)
b(15m)
c(-30m)
d(-20m)
e(10m)
f(5m)
what is the distance from point b to point e

85 m

Explanation:

In order to calculate the distance travelled from point B to point E, we need to add all the distances covered during the parts of the trip between B and E. So we have:

- From B to C:

- From C to D:

- From D to E:

So, the distance travelled from B to E is

d = 45 m + 10 m + 30 m = 85 m
