For a training run, a triathlete covers 50 km in 4 1/4 hours. She runs part of the way at a speed of 10km/h, cycles part of the way at 40km/h and swims the remaining distance at 2 1/2 km/h. The athlete runs for twice the time it takes to complete the cycle leg. How long did she take to complete the cycle leg? (If you can show your working out, I will give you brainliest). Thanks

step-by-step explanation: it is d

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
