Answer:
The correct option is C) 24 min.
Step-by-step explanation:
It is given that:
Speed of Samir riding his bike = 6mph
Speed of Chris riding his bike = 9 mph
Let the time taken by Chris be x min. Then the time was taken by Samir be x+12
We know that the formula for the distance is

Answer:
2.18
Step-by-step explanation:
We will use angle A to solve this and tangent. Tangent in equal to opposite divided by adjacent. In relation to angle A, the opposite side is 6 units and the adjacent side is AC, which we want. This can be set up as
tan70=6/x (x is representing AC)
(x)tan70=6
x=6/tan70
x=2.18
