Answer:30km/hr
Step-by-step explanation:
Total distance=294km
Speed=s
Distance=d
Time=t
First drive:
t=5
d=s x t
d=s x 5
d=5s
Second drive:
t=4
Speed is 6km/h greater than the first speed
The new speed= s+6
d=4(s+6)
Total distance=294
5s + 4(s + 6)=294
5s + 4s + 24=294
Collect like terms
5s + 4s=294 - 24
9s=270
Divide both sides by 9
9s/9=270/9
s=30
First speed=30km/hr
Answer:
the number of time spend in reading is 31.3 minutes
Step-by-step explanation:
The computation of the number of time spend in reading is as follows:
= 9.75 pages in science book × 1.2 minutes + 24.5 pages in english class × 0.8 minutes
= 11.7 minutes + 19.6 minutes
= 31.3 minutes
Hence, the number of time spend in reading is 31.3 minutes
