E Explore It! A group of college students developed a

solar-powered car and entered it in a

race. The car travels at a constant speed

of 100 meters per 4 seconds.

50m/s

Step-by-step explanation:

Since we are not told what to find, we can as well look for two speed of the car in meter per seconds

If the car travels at a constant speed of 100 meters per 4 seconds, the we can say;

100 meters = 4seconds

Since we want to know the speed in metres per second, we will say;

X meters = 1second

Equating both

100 meters = 4seconds

X meters = 1seconds

Cross multiply

4×X = 200×1

4X = 200

Divide both sides by 4

4X/4 = 200/4

X= 50

Hence the of the car in meter per seconds is 50meters per second

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
