Answer:
2.988*10^8
Step-by-step explanation:
to do standard form you have to move the decimal to after the first number so in this case we would move the decimal 8 places from 298800000.0
to 2.98800000 and we can remove the zeros to make it 2.988
then you will plug the times ten and because we move the decimal over 8 it would be 10 to the power of 8 so your answer would be 2.988*10^8
hope this helps have a good day

Answer:
t= 2.52 hours
Step-by-step explanation:
It is given that for first 30 km, the speed of bicyclist is v km/hour
time taken to cover first 30 km is given by
( )
for next 17 km the speed of bicyclist is 2 km/hour greater than his original speed
so the speed to cover next 17 km = v+2
time taken to cover next 17 km is given by
now total time t spent by the bicyclist to cover entire trip is given by
now if v=18 , we have
now to add fractions we make the denominator same
Hence we will find the LCM of 18 and 20
LCM of 18 and 20 = 180
now we need to make both the denominator equal to 180
