3/8=.375
.375 move the decimal two times to the right to make it a percent so it would be 37.5%

Answer:
a) 1000 ftft
Step-by-step explanation:
sin 30 = 500/dist
dist = 500/sin 30 = 1000
Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
