An object is traveling at a steady speed of 9 and nine tenths
km/h. how long will it take the object to travel 5 and one tenth km
? find the exact answer. brainliest to first who answers

i think it would be 0.5152 hours

Step-by-step explanation:

if it goes 9.9 km in 1 hour, how long would it take for it to go 5.1 km

9.9km/1hr = 5.1km/xhr

(5.1km × 1hr) / 9.9km = xhr

5.1/9.9 = 0.5152

so about 0.5152 hours i think

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

5 + 8 +7 + 4 + 0 +1 = 25
