First, ignore the whole numbers and come back to them later. Add the numerators which is 5+9= 14. Keep the common denominator the same so it would equal 14/10. Make 14/10 into a mixed number which is 1 4/10. Simplify the 4/10 to 2/5 so now you have 1 2/5. Now come back to the whole numbers 4+6= 10. Finally add 10+1 2/5. Your answer is 11 2/5.

A train goes twice as fast downhill as it can go uphill, and 2/3 feet as fast uphill as it can go on level ground. If it goes 12
Yuri [45]

Answer:

0.5hrs

Step-by-step explanation:

Let the speed downhill be x,

Speed uphill is 0.5x. We are told than speed uphill is \frac{2}{3} the speed on flat ground. Therefore the speed on level ground will be \frac{0.5x}{2/3}=0.75x.

From this info, we can obtain the actual speed,v_g on level ground as:

x=120m/h\\0.75x=v_g\\\\\therefore v_g=\frac{0.75x \times 120m/h}{x}\\v_g=90m/h

speed, distance and time have the relation s=d/t so to obtain time to cover 45miles:

t=d/s\\=45/90\\=0.5h

Hence it takes 0.5hrs to cover 45miles on flat ground.
