I'll assume the question is whether the tourists will all fit.
15 vans × 9 tourists each van = 135 tourists can fit so he needs another van or 5 of them have to hold on to the roof of the car

A commercial jet can fly 868 miles in 2 hours with a tailwind but only 792 miles in 2 hours into a headwind. Find the speed of t

erik [133]

Answer:

The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the speed of the wind in miles per hour

y ----> the speed of the jet in still air in miles per hour

we know that

With a tailwind

$y+x=\frac{868}{2}$

$y+x=434$ ----> equation A

With a headwind

$y-x=\frac{792}{2}$

$y-x=396$ ----> equation B

solve the system of equations A and B by elimination

Adds equation A and equation B

$y+x=434\\y-x=396\\------\\y+y=434+396\\2y=830\\y=415$

Find the value of x

$y+x=434$

$415+x=434$

$x=434-415$

$x=19$

therefore

The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph

Kali left the White House and traveled toward the lake. Ndiba left one hour later traveling 15 mph faster in an effort to catch

CaHeK987 [17]

Answer:

The speed of Kali is 30 mph.

Step-by-step explanation:

Let, the speed of Kali be "x", then speed of Ndiba will be:

Speed of Ndiba = x + 15 mph

If, the time for travel for Ndiba is 2 hrs, when he catches Kali, and he left 1 hour later than Kali, then then time traveled by Kali at that instant will be 2+1 = 3hrs.

At the point of meeting both will have covered same distance.

Distance Covered by Kali = Distance Covered by Ndiba

(Speed of Kali)(Time traveled by Kali) = (Speed of Ndiba)(Time traveled by Ndiba)

(x)(3) = (x +15)(2)

3x = 2x +30

x = 30 mph

The correct answer is, actually 30 mph, by the solution shown above.

-4 since -4*-15=60
