Answer:
x ≈ 32.3
Step-by-step explanation:
Using the sine ratio in the right triangle
sin48° =
=
( multiply both sides by x )
x × sin48° = 24 ( divide both sides by sin48° )
x =
≈ 32.3 ( to 1 dec. place )
10 blocks = 6 min
30 blocks = 18 min
You can answer this because you know that 10 x 3 is 30, so if if the number of blocks tripled then the amount of time should triple as well because he's running at the same rate.

7.35 x 10 (22) kg ( I think )
[2] \frac{x}{y} [/3]*[1] \frac{x}{y} [/3]=[2] \frac{x}{y} [/9]
2*1=2
3*3=9
