James and Lucas competed in climbing a mountain and coming back. James climbed at an average rate of 3 mph and ran back at 4 mph

Bogdan [553]

It took 70 minutes for James to finish and 84 minutes for Lucas to finish and James was faster.

Step-by-step explanation:

Given,

Climbing rate of James = 3 mph

Running back rate of James = 4 mph

Climbing rate of Lucas = 2 mph

Running back rate = 5 mph

Total distance = 2 miles

We know that;

Distance = Speed * Time

As we have to find, we will rearrange the formula in terms of time

$Time=\frac{Distance}{Speed}$

Time took by James for climbing = $\frac{2}{3}\ hours$

Time took for running back = $\frac{2}{4}\ hours$

Total time = $\frac{2}{3}+\frac{2}{4}=\frac{8+6}{12}=\frac{14}{12}$

Total time taken by James = $\frac{7}{6}\ hours$

1 hour = 60

Total time taken by James = $\frac{7}{6}*60=70\ minutes$

Time took by Lucas for climbing = $\frac{2}{2}=\ 1\ hour$

Time took by Lucas for climbing = 60 minutes

Time took on return = $\frac{2}{5} of\ an\ hour=\frac{2}{5}*60=24\ minutes$

Total time taken by Lucas = 60+24 = 84 minutes

Therefore,

It took 70 minutes for James to finish and 84 minutes for Lucas to finish and James was faster.

Pls solve this<br> we need to find radius of this shape

Strike441 [17]

(not sure )
my method
let projection of b onto line dq be M
BM is 2r
then let the remaining angle ( right) be K
in triangle BMK ,
MK = 29-5-r
By Pyth. theorem ,
23^2 = (2r)^2+(29-5-r)^2
529=4r^2+576-48r+r^2
5r^2-48r+47=0
r = 8.493237063 or 1.106762937(rejected)
